Play as an astronaut-clad star ranger exploring procedurally generated metal space-station corridors. Tap monsters to fire your laser remotely, manage energy (attacks cost 10, auto-regen, pick up cells) and shields (absorb damage, regen out of combat), navigate low-gravity and high-gravity zones, descend deck by deck, loot tech crates, and spend growth points on energy cap, shield regen, and starting energy.
